This study is to assess the effectiveness and outcome of the AO titanium volar distal radius plate (Synthes) in the treatment of peri-articular volar rim fractures of the distal radius. It was conducted on 22 patients with distal radius fractures who underwent open reduction, internal fixation using the AO titanium volar distal radius plate between July 1998 and December 1999 at the Changi General Hospital. The radiographs of the patients were analysed upon fracture union and assessment of wrist function was done using Gartland and Werley criteria. There were four extra-articular AO Type A2(1) and A3(3): the remaining 18 intra-articular fractures consisted of AO B3(2), AO C1(11), AO C2(2) and AO C3(3). The average follow-up period was 12.6 months (range 7-23). Radiological review showed bone healing in 21 patients (95.5%) and good articular congruity for all intra-articular fractures with less than 2 mm step-off. Three patients defaulted follow-up. Complications were few with one wound infection, one tendon rupture and three neuropraxia of the superficial radial nerve. Wrist function was excellent in three patients, good in 12 and fair in four. The AO titanium plate with its distal buttressing ability is an effective treatment modality in patients with distal radius fractures involving the peri-articular volar rim.
本研究旨在评估AO钛制桡骨远端掌侧钢板（辛迪斯公司）治疗桡骨远端关节周围掌侧缘骨折的有效性及疗效。研究对象为1998年7月至1999年12月在樟宜综合医院接受切开复位、使用AO钛制桡骨远端掌侧钢板内固定治疗的22例桡骨远端骨折患者。骨折愈合时分析患者的X线片，并采用加特兰和韦利标准对腕关节功能进行评估。有4例为关节外AO A2(1)型和A3(3)型骨折；其余18例关节内骨折包括AO B3(2)型、AO C1(11)型、AO C2(2)型和AO C3(3)型。平均随访期为12.6个月（范围7 - 23个月）。影像学复查显示21例患者（95.5%）骨折愈合，所有关节内骨折关节面平整，台阶小于2 mm。3例患者未按要求随访。并发症较少，1例伤口感染，1例肌腱断裂，3例桡浅神经神经失用。3例患者腕关节功能优，12例良，4例可。AO钛板具有远端支撑能力，是治疗累及关节周围掌侧缘的桡骨远端骨折患者的一种有效治疗方式。
